Come limitare l'impatto dei consumi di energia sull'uomo e sull'ambiente, senza compromettere lo sviluppo economico? Un impiego delle fonti rinnovabili, e in particolare dell'energia solare, è ormai ritenuto necessario e possibile, anche in ampie proporzioni. Nel volume si discutono gli aspetti tecnologici ed economici dello sfruttamento dell'energia solare e si offre un quadro delle politiche nazionali e dell'Unione europea nel settore.

Barcellona, Manchester o Salonicco, Torino, Bari o Genova: cosa hanno in comune queste città? Il fatto che possono essere considerate smart, misurandole con diversi parametri che vanno dai trasporti all'istruzione, dalla sanità alla sostenibilità ambientale all'innovazione tecnologica. Smart city è dunque una definizione complessa cha allude ad una trasformazione delle nostre attuali città con l'obiettivo non solo del superamento delle emergenze energetiche ed ambientali, ma anche della qualità del vivere per il cittadino e per la comunità, sul piano sociale ed economico.

L'economia mondiale si è sviluppata nel secondo dopoguerra grazie alla grande disponibilità dei combustibili fossili senza che si tenesse conto né del vincolo di scarsità, né dell'impatto sull'ambiente che la loro combustione comporta. Oggi ci troviamo costretti a ripensare le scelte di approvvigionamento energetico.

Sols contaminés, eaux souillées, rejets toxiques, etc. Si la présence de polluants dans la biosphère remonte à la nuit des temps, l'augmentation de la population de la planète et l'accroissement des activités humaines ont provoqué une multiplication des cas de pollution depuis le début de l'ère industrielle.

Le réchauffement climatique et le rôle des activités humaines sur notre climat deviennent de plus en plus perceptibles et occupent une place grandissante dans notre vie quotidienne. Lutter contre le réchauffement climatique est un véritable défi : c'est celui que s'est fixé Jean Jouzel tout au long de sa carrière scientifique.

La situation critique dans laquelle se trouve la planète n'est plus à démontrer. Des effondrements sont déjà en cours tandis que d'autres s'amorcent, faisant grandir la possibilité d'un emballement global qui signifierait la fin du monde tel que nous le connaissons. Le choix de notre génération est cornélien : soit nous attendons de subir de plein fouet la violence des cataclysmes à venir, soit, pour en éviter certains, nous prenons un virage si serré qu'il déclencherait notre propre fin-du-monde-industriel.

Transition énergétique, révolution numérique, mutation écologique... Politiques, médias, industriels nous promettent en chœur un nouveau monde enfin affranchi du pétrole, des pollutions, des pénuries et des tensions militaires. Cet ouvrage, fruit de six années d'enquête dans une douzaine de pays, nous montre qu'il n'en est rien ! En nous émancipant des énergies fossiles, nous sombrons en réalité dans une nouvelle dépendance : celle aux métaux rares. Graphite, indium, tungstène, terres rares.

With multiple studies backing its findings and thorough explanations for each technique, The Secret Therapy of Trees is a treasure trove of tips on how to harness the regenerative power of plants and reconnect with our planet's natural spaces, bringing us health and happiness. You'll also discover: which plants purify the environment at home and in the office, the benefits of negative ions and where to find them, and how to recharge through contact with trees.

An engaging guide to the art of forest bathing, inspired by the Japanese practice of shinrin-yoku, for anyone who wants to explore the transformative power of nature in promoting health and happiness.

Every cow just wants to be happy. Every chicken just wants to be free. Every bear, dog, or mouse experiences sorrow and feels pain as intensely as any of us humans do. In a compelling appeal to reason and human kindness, Matthieu Ricard here takes the arguments from his best sellers Altruism and Happiness to their logical conclusion: Compassion toward all beings, including our fellow animals, is a moral obligation and the direction toward which any enlightened society must aspire.

As development and subsequent habitat destruction accelerate, there are increasing pressures on wildlife populations. But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity. Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and this audio edition will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

In The Marsh Builders, Sharon Levy delves into the intertwined histories of wetlands loss and water pollution. The book's springboard is the tale of a years-long citizen uprising in Humboldt County, California, which led to the creation of one of the first US wetlands designed to treat city sewage. The book explores the global roots of this local story: the cholera epidemics that plagued 19th-century Europe; the researchers who invented modern sewage treatment after bumbling across the insight that microbes break down pollutants in water; and more.

At a time of unparalleled environmental change, there has never been a greater need for new ways of defending nature. In this forward-thinking work, Paul Jepson and Richard Ladle cover all aspects of modern conservation to provide a fascinating look into how we’re fighting for the earth’s species and habitats, as well as details on where conservation is heading, and how we can all contribute. Because it will be far more than just a pity when we lose the polar bears, pandas, and parrots.

We should thank a pollinator at every meal. These diminutive creatures fertilize a third of the crops we eat. Yet half of the 2,000 species of pollinators are threatened. Birds, bats, insects, and many other pollinators are disappearing, putting our entire food supply in jeopardy. In North America and Europe, bee populations have already plummeted by more than a third and the population of butterflies has declined 31 percent. Protecting Pollinators explores why the statistics have become so dire and how they can be reversed.

One cannot turn on the news today without a report on an extreme-weather event or the latest update on Antarctica. But while our politicians argue, the truth is that climate change is already here. Nobody knows this better than Indigenous peoples, who, having developed an intimate relationship with ecosystems over generations, have observed these changes for decades. For them, climate change is not an abstract concept or policy issue, but the reality of daily life.

The smog beast wafted into downtown Los Angeles on July 26, 1943. Nobody knew what it was. Secretaries rubbed their eyes. Traffic cops seemed to disappear in the mysterious haze. Were Japanese saboteurs responsible? A reckless factory? The truth was much worse - it came from within, from Southern California's burgeoning car-addicted, suburban lifestyle. Smogtown is the story of pollution, progress, and how an optimistic people confronted the epic struggle against airborne poisons barraging their hometowns.

Most of us have heard of such popular butterflies as the Monarch or Painted Lady. But what about the Fender's Blue? Or the St. Francis' Satyr? Because of their extreme rarity, these butterflies are not well-known, yet they are remarkable species with important lessons to teach us. The Last Butterflies spotlights the rarest of these creatures - some numbering no more than what can be held in one hand.

Humanity has become profoundly disconnected from the web of life on Earth as well as from nature as a whole. In this practical guide, Elizabeth E. Meacham details her field-tested method of shamanic ecotherapy practices to resolve this centuries-long trend toward disconnection. Through these practices, you will learn how to reconnect to Earth's systems and help restore health and balance to people and the planet.

For our ancestors, collective intelligence was a normal part of life. We see it today as the mysterious force that enables flocks of birds, swarms of bees, and schools of fish to function together in perfect synchrony, communicating and cooperating at some undetectable level. At its most subtle, it’s an instantaneous knowing, shared by members of a group, of the wisest course of action that will benefit all.

Award-winning author Thom Hatch presents the definitive biography of George Bird Grinnell (1849-1938), who was recognized in his time as "The Father of American Conservation." This book chronicles not only Grinnell's life, but also offers a history of his accomplishments in saving the wildlife and natural resources of this country. A remarkable man, Grinnell was known as a model of intellectual diversity, integrity, and professional dedication.
